Swabs were taken from the posterior fornix, perineum, and anorectum of 135 patients on three occasions during their pregnancy. Multiple isolates of beta-haemolytic streptococci of group B were obtained from 24 women, in 21 of whom the strains were examined by a highly discriminative serotyping and phage typing method. In 18 of these patients their own isolates were indistinguishable but different from those of other women with multiple isolates. Women yielding group B streptococci from the posterior fornix usually carried an indistinguishable strain in the anorectum.
在135名孕妇孕期的三个不同时间,从她们的阴道后穹窿、会阴和肛门直肠采集拭子。24名女性分离出了多种B族β溶血性链球菌,其中21名女性的菌株通过高分辨率血清分型和噬菌体分型方法进行了检测。在这些患者中,有18名患者自己的分离株无法区分,但与其他有多种分离株的女性不同。从阴道后穹窿分离出B族链球菌的女性,其直肠中通常携带无法区分的菌株。
